Tank description:

The O-I is a Japanese tier 6 heavy tank.Development of the superheavy tank was started after the Battles of Khalkhyn Gol in 1939. The vehicle was designed as a maneuverable fire unit that was unprecedented in scale—its hull alone weighted 100 tons. Only one prototype was built, without a turret and made of construction steel. Trials were discontinued due to the unreliable engine; at the end of 1944, the prototype was scrapped. The 15-cm howitzer was to be mounted on the tank after the assemble.Also known as Derp Demon or Emperor of Derp. It can withstand even higher tiers with its thick armor and derp gun. However, like every Japanese heavy tank after tier 4, it is huge and massive, and will usually become the primary target of SPGs.The O-I leads to
the O-Ni.
